Monkeys are like people tend to keep up, scientists have found

People have been known to unconsciously adjust their movements under the people nearby - go for a walk in the foot or clap in rhythm during the concert.Monkeys as well as humans, tend to synchronize their movements with their neighbors and move them at the same pace, scientists have found out of the Institute for Brain Research Center of Japanese RIKEN. People have been known to unconsciously adjust their movements under the people nearby - go for a walk in the foot or clap in rhythm during the concert. The group, led by Dr. Naotaka Fujii (Naotaka Fujii) in experiments with Japanese macaques found Read more [...]

Frequency of the noise

Frequency of the noise is due to standing waves are formed in the propagation of electromagnetic waves around the Earth. It is believed that the excitation is due to lightning.Frequency of the noise is calculated very simply. Take the speed of light 300,000 km / c and is divided by the circumference of the Earth 40,000 km and 7.5 Hz is obtained for the first harmonic. Given that the wave travels between the Earth and the ionosphere radius increases and turns, just 7.8 Hz (first harmonic), as shown by instruments.I am embarrassed that the cause of excitation considered lightning, though perhaps Read more [...]

The detection rate of arrhythmia

Published data on the incidence of cardiac arrhythmias in athletes contradictory. One reason for these discrepancies is the above mentioned lack of uniform criteria for the diagnosis of certain cardiac arrhythmias. Another, equally important reason is the lack of a common methodology ECG arrhythmia research and scientific evidence on the impact of the duration of ECG for detection rate of various arrhythmias. Time ECG has no appreciable effect on the frequency of detection of arrhythmias, accompanied by changes in timing atrio-ventricular complex (cross-site block, atrioventricular block I degree, Read more [...]

The reasons for the frequency of sleep biological clock

As we have seen, for the natural sleep of animals and humans is characterized by periodicity, although the duration of these periods can be very different. What is the reason this periodicity? For seasonal hibernation of animals we have concluded that her periods are due to adverse seasonal conditions. Well, dream man? Why in the world most people sleep at night and stay awake during the day? Is it possible to alter the rhythm and how it is durable? Only a day and night (Ie, light and dark) define the rhythm of sleep and as is the case, for example, the polar night? All these questions are Read more [...]

Violations of automatism

Violations of automatism normosistolicheskogo types account for more than half of all violations of automatism found in athletes. ECG and rhythm and graphical analysis of cases pronounced sinus arrhythmia can allocate some of its variants, the most typical of the increase or decrease the impact on the aperiodic rhythm, transiently appear against the background of respiratory periodicals. Polifokusny driver rhythm for breach normosistolicheskogo type characterized by a smooth transition from the driver's sinus node in the atrium and back to the sinus node in sync with the phases of respiration. As Read more [...]

The components of the electroencephalogram (EEG) and its properties

Electroencephalographic equipment has enabled an objective assessment of bioelectric phenomena observed in different parts of the brain of animals and humans. Thus, it was found that the healthy adult human EEG in the waking state is a complex curve, which shows the frequency analysis can be broken down into a number of components of the oscillations (Fig. 3). Predominant in human EEG is rhythm with a frequency of 8-13 c / s, which is still called Berger alpha rhythm. Activity 14-30 kol1sek called beta rhythm, and the frequency of 31 c / s and above - the gamma rhythm. An EEG observed slower Read more [...]

Gallop rhythm

Gallop rhythm - Is a three-term cardiac rhythm, reminiscent of the sound of a galloping horse, is determined by listening to the heart in patients with damage to the heart muscle. At a gallop rhythm, addition to the usual two-tone, time diastolic heart auscultated quiet third tone, accompanied by a push. He is best revealed in the immediate auscultation ear. Gallop rhythm may occur in myocardial infarction, uncompensated heart defects, myocarditis, hypertension, severe cardiosclerosis, chronic nephritis, and serves as an important sign of the weakness of the heart muscle. Read more [...]

Physiology of the reproductive function of women

That woman's body provides the conditions for the occurrence of pregnancy, fetal growth and development, birth and infant feeding. Biological female reproductive system reliability is ensured not only by the process of overproduction of sex cells, but also the specific rhythm of work - a recurring monthly basis to create the conditions for pregnancy. In the absence of this pregnancy rhythm manifests the appearance of menstrual bleeding from the uterus to the exclusion of its internal functional layers - the endometrium. Menstrual bleeding usually occur at intervals of 21-35 days (usually Read more [...]

Arrhythmia caused by dysfunction of the heart automaticity

These arrhythmias can be divided into two groups. The former include sinus tachycardia, sinus bradycardia and sinus arrhythmia, in which the starting point of the heartbeat is sinus node - Nomotopny rhythm, changing only the number or sequence of pulses coming from the site. The second group of atrio-ventricular rhythm, the migration of the source of heart rhythm, interfering dissociation, termination of atrial contractions, idioventricular rhythm in which a rack or temporarily change the reference point and a source of excitation of the heart rhythm instead of the sinus node is any other point Read more [...]

Antiarrhythmic drugs (antiarrhythmic drugs) - substances that affect the excitability and conductivity heart muscle and thereby normalizing heart rhythm. By antiarrhythmic agents include quinidine and procainamide. Quinidine and procainamide reduces anxiety attack to slow the passage of impulses along the cardiac conduction system, in large doses, can lower heart rate and strength, and quinidine more than procainamide. Both of these tools are used for atrial fibrillation, paroxysmal tachycardia, arrhythmia. Contraindications to the use - see procainamide, quinidine. As antiarrhythmics used as Read more [...]

Mismatch rhythm of sleep and wakefulness

In the course of its development, people like to "fit" into a temporary structure defined by the Earth's rotation on its axis and the sun. Numerous biological experiments showed that all living organisms (from single-celled plants and animals to humans included) daily rhythms of cell division activity and rest, metabolism, health, and so on, in constant conditions (constant light or in the dark) are very stable, approaching the 24-hour periodicity. At present in the human body there are about 300 processes exposed daily periodicity. Under normal conditions, "circadian" Read more [...]

Site "Survival in the wild nature", glad to see you. If you come to us, it means you want to get complete information about survival in a variety of extreme conditions, in emergency situations. Man, throughout the development, sought to preserve and protect themselves from the various negative factors surrounding it - cold, heat, hunger, dangerous animals and insects.

Site structure "Survival in the wild nature" is simple and logical, selecting a specific section, you will find information. You will find on our website recommendations and practical advice on survival, unique descriptions and pictures of animals and plants, turn-based scheme to trap wild animals, tests and reviews of travel gear, rare books on survival and wildlife. The site also has a large section devoted to video on survival survivalist-known professionals around the world.

The main theme of the site, "Survival in the wild nature" - is to be ready to be in the wild, and the ability to survive in extreme conditions.

The Survival in the wild nature - how correctly to behave, it having appeared in an emergency situation. Ability to find a way out from any situation: to kindle a fire, to put traps, to prepare food, to arrange dwelling and a lodging for the night; to learn to knit knots, to clear water, to be guided by districts, correctly to choose equipment, a knife. Also you can download directories to tourists, encyclopedias survivals, video Bear Grills to Survive at any cost (Man vs. Wild).
